METALLIC RAILWAY-TIE.

SPECIFICATION forming part of Letters Patent No. 782,317, dated.February 14 1905.

Application filed May 16, 1904. $eria1 No. 208,124.

To all whom it may concern.-

Be it known that we, J Aims HOLMES BLAIR, of Pittsburg, and FRANKDITCHFIELD, of Bellevue, Allegheny county,Pennsylvania, have invented anew and useful Metallic Railway-Tie, ofwhich the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification, in which Figure 1 is a topplan view of our improved tie. Fig. 2 is a side elevation of the same,partly in section. Fig. 3 is a cross-section through thestrengthening-rib at one side of the filler-block. Figs. 4 and 5 areviewssimilar to Figs. 1 vand 2, respectively, showing a modified form;and Fig. 6 is a cross-section of such modified form.

Our invention relates to the class of metallic railway-ties, and isdesigned to provide a cheap, simple, and effective tie wherein the railsare cushioned by the use of a wooden filler-block.

The invention consists in a channel-shaped metal tie having the flangescut out or notched on opposite sides to receive transverse fillerblocks.

It also consists in a channel-tie having bentup lugs to hold thefiller-blocks in place, in'a strengthening-rib arranged .below theblock, and, further, in the construction and arrangement of the parts,as hereinafter more fully described and claimed.

In the'drawings, referring to the form of Figs. 1, 2, and 3, 2represents the ,web, and 3 3 the flanges, of a channel-section, whichare preferably formed of pressed steel. The flanges are notched orslotted at opposite sides near the ends, these notches preferably beingof the dovetailed form, and within these notches are seated thetransverse wooden blocks 4, the sides of which are beveled or inclinedto fit the edges of the flanges in the notched portions. In order tohold the fillerblocks in place, we show the flanges as havinginwardly-bent lugs 5, which may be formed in slotting them. These lugsfit against the inclined faces of the block and prevent its movementlengthwise of the tie. The fillerblock is preferably of such length thatits ends scribed.

are flush with the side flanges, though it may extend beyond them, ifdesired, and toprevent the movement of the block we preferably form thelugs 5 with notches, beneath which nails or spikes 6 may be driven intothe blocks. The rails are spliced to the filler-blocks in the usualmanner, and the grain of these blocks preferably runs in line with theaxis of the tie at right angles to the rail. To strengthen the tie inthe portions beneath the rails, we preferably form depending ribs 7,which may be pressed into shape when the plate is pressed into channelform. These ribs preferably extend from the ends of the tie inwardlybeyond the filler-blocks. In order to allow drainage from the interiorof the inverted channel, we

preferably form a slot or slots 8 8 in the intermediate portion of itsweb to allow moisture to drain out.

vThe form of Figs. 4, 5, and 6 is similar to the first form except thatinstead of forming lugs in the side flanges lugs 9 are cut and bent upfrom the web, these lugs fitting against the ing the blocks in place.

Variations may be made in the form and arrangements of the various partswithout departing from our invention.

We claim 1. A metallic tie comprising. ametal web having notched orrecessed side flanges near its ends and filler-blocks seated in therecessed portions of said flanges, substantially as de- 2. A metallictie comprising an inverted channel with its flanges recessed or notcheddown to the web, and filler-blocks, seated in the recessed portion;substantially as described.

3. A metallic tie comprising an inverted channel with dovetailedrecesses in the side flanges extending down to the web, and blockshaving inclined sides fitting in said recesses; substantially asdescribed.

4. A metallic tie comprising an inverted channel with recessed sideflanges near its ends, filler-blocks seated in the recessed portions,and depending ribs in the web extending beneath the filler-blocks;substantially as de-- scribed.

5. A metal tie of inverted-channel form, having filler-blocks, and lugsbent up from the tiebody against the inner and outer faces of thefiller-blocks, and arranged to prevent movement thereof in eitherdirection lengthwise of the tie; substantially as described.

6. A metallic tie comprising an inverted blocks; substantially asdescribed.

In testimony whereof We have hereunto set our hands.
